Hi all;
I'm getting wildly inconsistent results... when I first connected to the wireless at a client site today I got speeds up to 25Mbps!
Later the wireless disconnected and then cycled through asking me for the password over and over and never connecting... since then the few times I did get connected I could not even go to a web page, it tried for awhile then disconnected again
Any help debugging this would be appreciated. In the meantime, does Fedora play well with USB wireless cards/devices? would it be worthwhile to grab a USB wireless card while I try and work through this?
I've not run into the situation you're describing....
It may be helpful to learn what hardware is involved. For your laptop, you can do lspci, assuming the wifi is on the PCI bus, or lsusb if it on the USB bus. Also you can do "ifconfig" and look for the number associated with "ether" and look that up on http://www.macvendorlookup.com/ .
To find out the hardware of the AP you would do iwconfig and use the Access Point: information.
As for USB dongles, the ones that have been on the market for a while are normally supported. There probably is a site which lists tested models...you can google that.
Mine is....
Bus 001 Device 004: ID 0411:015d BUFFALO INC. (formerly MelCo., Inc.) WLI-UC-GN Wireless LAN Adapter [Ralink RT3070]
and works fine.
